Alex, I understand your point and appreciate your input highly, but let's say that asterisk is needed as the media server for other reasons. It may not scale as well as the other solutions but we need them to be there to provide other services. I just wanted to know whether there was any difference aside from the scalabilty issue. We were under the impression that it was imperative to use either media-proxy or rtp-proxy but after examining in more detail how the 2 solutions work we find no reason not to use asterisk as the media proxy as well. Unless of course we are missing the big picture here and surely will find out once we set out to test it. But given the deep knowledge of a lot of people in this forum we deemed necessary to ask about the feasibility of this workaround. If somebody detects any flaw on this solution or if there is someting else critical or not that we are missing we would love to hear it . thank you in advance and thank you Alex again, jp ----- Original Message ---- From: Alex Balashov <abalashov(a)evaristesys.com> To: Juan Perez <jperezsip2008(a)yahoo.com> Sent: Monday, March 16, 2009 6:51:34 PM Subject: Re: [Kamailio-Users] Using Asterisk as media server No, because the amount of throughput you get per media/RTP proxy is much higher than you would get through something whose entire core is structured to behave as a PBX, with all the attendant features and latent event loop characteristics. A media relay does one thing and one thing only, and it does it well. Asterisk does many things, among them media relay. So, while you could use Asterisk in this capacity, I don't see the point. It'd be a waste of time. Also, you don't really want to get Asterisk involved in the signaling layer (as a B2BUA) if you can help it. It introduces unnecessary complexity and possible points of interop problems and failure. With a media relay that is controlled by API hooks into Kamailio, you don't have that problem.

thank you very much guys, your comments are highly appreciated, unfortunately it is not up to me to decide the media gw to use.
